Dell, today, is launching a special PowerShell provider for native configuration of Optiplex, Latitude, Precision, and Venue 11 systems. Currently in beta, you can download the new provider, test it for bugs, and then report issues in the Dell TechCenter forums.
The beta page includes the download, script example, and a really short set of FAQs, which include things like PowerShell version requirements, special driver installation, and WinPE support.
You can find everything here: Dell Client PowerShell Provider
Feedback, discussions, and bug submissions happen in this forum starter: Dell Client PowerShell Provider Beta now available
To download the actual beta provider, Dell has a form setup where you have to enter the normal stuff like name, company, email and other things.
